boolean |
allPathsAreWithinStreamableSnapshot() |
Determine whether the path is entirely within a streamable snapshot of a streamed document:
that is, it must only navigate to ancestors and to attributes of ancestors
|
PathMap.PathMapNode |
createArc(byte axis,
NodeTest test) |
Create a new arc
|
void |
createArc(byte axis,
NodeTest test,
PathMap.PathMapNode target) |
Create a new arc to an existing target
|
PathMap.PathMapArc[] |
getArcs() |
Get the arcs emanating from this node in the PathMap
|
boolean |
hasReachableReturnables() |
Test whether there are any returnable nodes reachable from this node by
zero or more arcs
|
boolean |
hasUnknownDependencies() |
Ask whether the path has unknown dependencies, typically because a node reached
by the path is supplied as an argument to a user-defined function
|
boolean |
isAtomized() |
Ask whether the typed value (or string value) of the node reached by this path
will be required.
|
boolean |
isReturnable() |
Ask whether the node represents a value that is returnable as the result of the
supplied expression, rather than merely a node that is visited en route
|
void |
setAtomized() |
Indicate that the typed value or string value of the node reached by this path
will be used.
|
void |
setHasUnknownDependencies() |
Indicate that the path has unknown dependencies, typically because a node reached
by the path is supplied as an argument to a user-defined function
|
void |
setReturnable(boolean returnable) |
Indicate that the node represents a value that is returnable as the result of the
supplied expression, rather than merely a node that is visited en route
